Mercury V8 V250 Outboard Key Features

V8 Power. No Excess Weight.

The 4.6L quad-cam V8 delivers serious mid-range punch with that unmistakable “slingshot” torque - yet it’s still one of the lightest engines in its class. Big performance. Smart balance.

Holds RPM in Real Conditions

Adaptive Speed Control automatically maintains your chosen RPM in turns, chop or while towing. No constant throttle adjustment. Just smooth, steady power.

Smooth. Quiet. Refined.

Mercury V8 V250 - 4 Stroke Engine Outboard FAQs

Is 250HP enough for my boat?
For most boats between 7m–9m (23–30ft), a single Mercury V8 V250 is more than enough for strong, confident performance.

• Ideal for larger RIBs, fast fishers, walkaround and sports cruisers
• Delivers strong mid-range torque for quick planing
• Handles full crew and gear without feeling strained

If your hull’s maximum rating is 250HP, this engine will let it perform exactly as designed. If you’re regularly heavily loaded or chasing maximum top-end speed, some owners consider twin setups or 300HP.

What top speed will I get?
It depends on hull, weight and prop, but typical figures are:

• 7.5 – 8m RIB: 45 – 55 knots
• 8 – 9m sports cruiser: 38 – 45 knots
• Comfortable cruising speed: 24 – 32 knots

The V8’s torque means it doesn’t need to be pushed hard to cruise efficiently.

Will the Mercury V8 V250 fit my transom?
The Mercury V8 V250 is available in Long Shaft (508mm), XL (635mm), and XXL (762mm). Always check transom rating and weight capacity.

How much does the Mercury V8 V250 weigh?
Approximate dry weight is 272KG for the lightest model available. For a naturally aspirated 4.6L V8, it’s relatively light in its class.

How noisy is the Mercury V8 V250?
It’s notably quiet for a V8. Smooth, low rumble at idle. Minimal vibration thanks to large displacement running at lower RPM. Quiet cruise compared to many high-revving competitors.

The industry-exclusive Advanced Sound Control feature lets you toggle between a whisper-quiet exhaust tone or a throatier growl at startup and idle, for those times you truly want to hear the horsepower.
